Are there any disadvantages to dispelling demons as they spawn from Fade Rifts

When a new wave of demons is in the process of spawning from an active Fade Rift, certain abilities like the Mage's Dispel, or the Templar Warrior specialisation's Spell Purge will insta-gib any demons they hit if they land before the demon spawns. Clearly this has the advantage of making the wave easier to deal with as you get fewer enemies spawning (or none at all in some cases). However, does doing this also have any disadvantages associated with it? For instance, do I get less XP? Less loot? Can I miss out on any Codex entries?

Alternatively, are they any reasons why I might not want to gib demons in this way and to just let them spawn?

Most of the enemies that are spawned from Fade Rifts don't drop regular loot, but they do all drop research items. Dispelling enemies before they're active means you won't get those at all. The research items are used to unlock Codex information, and even a damage bonus against researched enemies, so using Dispel throughout the game, especially to prevent the bigger enemies' appearing, can leave you a bit weaker against rifts by the end.
